| Abstract |
RSA is a well-known and widely used cryptosystem. One major limitation of RSA is its maximum input length depends on the chosen key size and the selected padding. This paper proposed a hybrid data compression algorithm to increase the input data length to be encrypted by RSA. Firstly, a plain text is compressed by LZW algorithm. The compressed data is padded. After that, the size of the compressed data is further reduced by using continued fraction. Double-compressed data is, then, used as an input of RSA. When using a combination of continued fraction and LZW algorithm, the results showed that, in average, the input data length is increased by 18.91 percent. In most cases, the processing time is much better than not doing any compression. In case of decryption, a cipher text is decrypted by RSA first. The padding is removed. Then, Euclidean algorithm and LZW are used respectively to restore the original data. The hybrid data compression is not only relieve the limitation of RSA but also enhances the security level. |
